User Profile

Hi,I need your help with a problem. In my app, I offer a registration for access to an online portal via Mac or PC. If the user completes a subscription for one month, he can register and log into the online portal.The problem is, however, if e.g. a company has linked all employee iphones with the same Apple ID. Then only one subscription has to be completed and another time, on a second device, is not possible, because then comes a message that this subscription has already been completed.Even if I link the subscription with a UserID and the DeviceID in the backend, the second device with the same AppleID can not complete the subscription. Right?Should every iPhone in this case have its own AppleID? That would of course be a big disadvantage, since certainly the company devices all use the same account for reasons of purchase.How can I solve this problem? I really want to use auto renewing subscriptions and no consumable purchases.Many thanks for your help!
